WATER-HEATER.

Specification of Letters Patent.

Patented Mar. 11,1913.

Application filed September 25, 1912. Serial No. 722,301.

To all whom, it may concern Be it known that I, LOUIS P. SILVERMAN, acitizen of the United States, and resident of the city of Providence, inthe county of Providence and State of Rhode Island, have inventedcertain new and useful Improvements in 'lVater-Heaters, of which thefollowing is a specification.

This invention relates to water heatels,

and has for its object to provide a small portable device of inexpensiveconstruction primarily designed to be connected by a rubber tube or thelike, to any ordinary water supply faucet and arranged to conduct andcirculate this water a number of times around the heated zone and overthe rising heat waves generated from beneath by a suitable gas burner,or other heat generator, to quickly and advantageously heat the water onits passage therethrough, and to finally discharge the heated waterthrough a suitable pipe to anydesired receptacle, such as a bowl or bathtub for bathing or other purposes.

An essential feature of my invention is the arrangement of watercirculating conductors or pipes wherebyin leading from one of thechambers or receptacles to another they are caused to pass through theconductors trans- $9 versely across the path of the-rising heat, by

which construction the heat is advantageously applied to raise thetemperature of the circulating water.

With these and other objects in View, the

invention consists of certain novel features of construction, as will bemore fully described and particularly pointed out in the appendedclaims.

Of the accompanying drawings: Figure 1- is a sectional elevation of myimproved heatershowing the water chambers arranged around the heatgenerator and the different pipes connecting the different chambers tocause the water to circulate 'a number of times therethrough before itis permitted to be discharged. Fig. 2 is a top view of the device withthe outer casing removed. Fig. 3-- is a plan view sectioned on line 3-3of Fig. 1.

.Referring to the'drawing, 10 designates a frame or base standing onlegs 11 for supporting the parts of the heater. Supported on this base{is a comparatively nolrrpw tubular ring 12 substantially rectangular in755 cross. section. Located just inside, of the upper edge of this ring12 is a comparatively tall annular chamber 13 through the center portionof which is formed a large flue 14, the side walls of which flue formthe inner walls of said annular chamber. This cham- 0 her 13 is divided"by the partition 15 into an upper compartment 16 and a separate lowercompartment 17.. The diametrically opposite port-ions of the uppercompartment.

of this body are connected by a plurality of 5 transverse pipes 26leading across the flue opening so that the heat in rising will act uponand quickly heat the water while circulating therethrough. Each of thesethree above-described water receptacles 12, 16 and 17 is separate anddistinct from the others and the only communication from one to theother is through a set of pipes or conductors presently described.

The water which may be led from an ordinary water supply faucet througha pipe, such as rubber tubing, or the like, not shown, may be connectedto the up-turned end 18 of the inlet pipe 19 the water passing throughsaid pipe down into the lower com- 30 partment of the chamber 13. Aftercirculating around through said compartment it passes upward through thetube 20 and transversely across the mouth of the openended flue 14,thencedown into the lower outer ring 12. After circulating aroundthrough said ring 12 it passes upward through the pipe 21 again acrossthe open' end of the flue 14 and down into the upper compartment 16 ofchamber 13, thence after circulating around the flue 14 it is permittedto pass out through pipe 22 to the end 23 to which may be connected anysuitable pipe or tubing. to conduct the heated water to any desiredreceptacle, such as a .95 bowl or bath tub.

The heat is preferably applied to this device by the burner 24 which issupplied with gas through the pipe 25, all of which. is supported fromthe frame 10. The arrangement of the chambers or receptacles is suchthat the outer ring 12 projects down beyond the lower wall ofcompartment 17 forming a fire box around the heater so as to retain theheat to act first upon the surrounding water containing chambers andthen to pass upward through theme-14 around and between the crosscirculating pipes 26 and the conductor pipes 19, 20, 21

and 22. In order to retainas muchof this heat as 'possibleeabout thewatenearrying members Lhave covered the whole casing 27 suitably ventedto permit the necessary draft for the burner and the same being slotteddown its side atthe points 28 and 29,'see Fig. 3, so as to also permitthe casing to pass readily over the protruding pipes, 19 and 22. Smallspring latches 30 are provi ed to hook over the frame Work so that; thewhole may be secured together provided with a transverse partitiondividing the same into upper and lower compartments, a heat generatingdevice acting on the lower end of said chamber, an independent waterring surrounding said lowercompartment and extending below the same toform a tire box, means for supplying water to said lower compartment, awater circulating conduct-or leading from said lower compartment to saidwater ring,- a second conductor leading from said ring to said uppercompartment, both of said con ductorsbeing extended transversely of thepath of travel of the heat. passing through said fine, and means forconducting the heated water from said upper compartment.

2. An improved water heater comprising a central heat conducting flue,an annular water chamber surrrounding said tine and provided with atransverse partition dividing the same into upper and lowercompartments, a heat generating device on the lower end of said chamber,an independent water ring surrounding said lower compartheatercomprising 'ment and extending below the same to form a fire box, meansfor supplying water to said lower compartment, a water circulatingconductor leading from said lower coinpartment to said water ring, asecond conductor leading from said ringto said uppercompartment, aninletconductor leading to said lower compartment, and an out-letv 0611-duct-or leading from said upper compartment, all ofsaid conductors beingextended transversely of the path of travel of the heat passing throughsaid flue.

3. An improved water heater comprising a central heat conducting flue,an annular water chamber surrounding said flue and provided with atransverse partition dividing "the same into upper and lowerconipartments, a heat generating device acting on the lowerend of saidchamber, an inde-' pendent water ring surrounding said lowercompartmentand extending below the same to form a fire box, means for siipplyiwater to said lower compartment, a water circulating conductor leadingfrom said lower compartment to said water ring, a

second conductor leading from said ring to Copies 51': this patent maybe obtained for five cents each, by addressing the Commissioner ofEatenta
